Heating is more costly if you use technology created for cooling. When you try to cool a cold space in order to heat hot space, you will have a bad time. You could use electric heater for heating, it should have no problems with heating, but will use more electricity. Or you could use something actually cheaper, like wood or fossil fuels. If you use more expensive method (like electricity) it will be more expensive.

This might be true for you. I have lived with free wood for heating and it was more expensive for me than using a heat pump. What is expensive depends on a lot of factors, political, social, location, time and knowledge. It is not a clear dollar per delta T.

Chopping up a tree is kind of fun, we bill that to the entertainment budget instead of the heating budget. And it usually happens during a hotter season, so I might have to go inside to take a break, get a cool drink. So, we can bill some of the tree chopping activity to the cooling budget!
